And now over to the business of the day.
Briz has been finished today. The chemo-fuelled upper stage is a small and quite easy one to make, however, the torus fuel tank parts on the top and bottom half need some attention when you build them.
After further detailing the lower torus with some aluminium tape strips, I made the central part of the stage. The outer ring shaped part of Briz is an external tank which can be jettisoned. The actual Briz stage is inside the ring. This ring shape was made by cutting out some cardboard rings in which the central doughnut-like opening is created. The hull goes around these rings. To get them snugly fitting I used some paper thickening inside the hull piece so it was tightly around the cardboard rings.
Also, the outside was detailed by carefully carving the textured lining.
more after the jump.
|The ring structure keeping Briz nice and round. Thick cardboard was used.|
|The skin is on. The textured part actually is textured by carving all the lines.|
|More rings. On the right is the lower part that fits on top of the Proton 3rd stage. The torus piece goes in here.|
|Torus in place.|
|Pressure tanks added (painted beads)|
|Upper torus part. Inside you might see the inner wall is extended to reach the edge of the rest of the wall.|
|Briz. One core engine and four vernier engines with a small pressure tank each.|
